Die Messung des Wasserpotentials mit der SCHOLANDER-Methode und ihre Bedeutung für die Forstwissenschaft

  • R. H. Waring

Summary

This deals with a method for determining the water potential of plants and soil and includes details of technique and application. The discussed procedure has found a wide following in the United States, but is nearly unknown in Europe. With different examples of forest research work it is shown that the procedure can be used in manifold ways, is very simple to handle and provides reliable dates. The principle is to place a detached leaf, a twig or a part of a living plant gastight into a steel container— just into the pressure bomb—in such a way that only the plan section is visible. Then the pressure inside the container is increased by means of compressed air or a nitrogen bottle until xylem water appears on the surface. The theory shows that the pressure read at this moment from the pressure gauge agrees with the water potential of the plant.
